It would be much more aesthetically pleasing if the grocery store was organized by color instead of food-type. When I say color, I'm talking about the color of the packaging if there is any or, if not, the color of the food. For example, bananas would be in the yellow aisle (although non-ripe bananas would be in the green aisle). Kraft Mac n Cheese would be in the blue aisle.
I think it would make the most sense if the colors were arranged the same as the rainbow from left to right, so violet/purple would be to the left of the grocery store and reds would be to the right of the store. It would be more enjoyable for both the people who work at the store and those of us visiting the store. Of course, it may be next to impossible to find anything, but that's the price you pay for aesthetics.
I'm going to talk to may local grocery store manager and I'd encourage you to do the same.
